Lightfast: very good.

Degradation processes: vermilion is, largely, a permanent pigment, its body and hiding power are stronger than those of cadmium red. However in the presence of hydrogen sulphides and sun light the pigment reacts chemically darkening to a black. Although it is a sulphide, it is so inert that it does not darken lead white when they are mixed and as a result they have often been mixed for flesh tints.

non toxic. Zinc white is not considered to be hazardous, but care should be used in handling the dry powder pigment to avoid inhaling the dust.
